)
from google.appengine.api import images
# ...
blob_keys = [..., ..., ..]
blob_key_serving_urls = []
Yes, you can cache the result. In practice, subsequent calls of
get_serving_url on the same blob should be faster, but if you have more new
blobs than old ones on a page it can be slow. The resulting URL only becomes
invalid if the blob is deleted.
